ABSTRACT:
A rotary tool for working in a cramped and possibly hostile environment. The tool can be clamped into position and left to work automatically. The tool has a resiliently biased pin and a ratchet driven cam for ensuring that the working unit cannot become overloaded. Working cannot go beyond a preselected level owing to the action of the ratchet driven cam which is only stepped to a certain level on a flange which strikes a lever when that level is reached. The work done can be cutting, welding preparation or trepanning.
